Another Info design website that concentrates on visual mapping rather than complex statistical analysis.
We remember images rather than text.
And developing a visual language that uses the basic design principles of line, form, color, texture, value is as important to the designer as creativity.
This particular website is a collection of visualizations from a variety of fields like social sciences, life sciences, social networks, etc.
Other visual techniques I like are :
Quick paper prototyping,
I use them extensively during brainstorming (for any problem:Creativity in Design and in Life) in the initial stages of a design process.
